Python-Web-Django: Building the First Web App

View Rendering

Edit views.py in the App directory

from django.shortcuts import render
from django.http import HttpResponse

# Create your views here.
def hello(request):
    return HttpResponse("Hello Django!")

URL Resolution Configuration

Edit urls.py: Add a URL resolution rule path('', views.hello) to urlpatterns

from django.contrib import admin
from django.urls import path
from hello_app import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', views.hello)
]

Building with Templates

Above we used django.http.HttpResponse() to output "Hello Django！". This approach mixes data with the view, which does not conform to Django's MVC philosophy. Next we will use an html template to build the App. In the previous article, we already configured the templates (templates) directory in settings.py. Now, create a home.html file in the templates directory.

Write the template file:

{% block main %}
    <h1>
        {{ home }}
    </h1>
{% endblock main %}

Define it in views.py

def home(request):
    context = {}
    context['home'] = "home"
    return render(request, 'home.html', context)

Configure URL resolution in urls.py

As mentioned earlier, this will not be repeated.
